Found Doc Anderson!!!

[Ricco]

Can't say exactly where, but a few meters South East from Gorski Cabin, just before the freeway.

She can be found from any random campfire spawn location. She have sometimes been in Concord spawn, right after I have cleared it from enemies.

i found her right behind the arc jet building you go to with palladin danse for the communication relay reciever thing.

usually in every playthrough i devote my biggest settlement to house all the recruitable traders. Doc Anderson, the Scribe, Smiling Larry, The Vault Tec Guy, Ron Staples, and Anne Hargreaves. All my level 4 shops in 1 location. Takes some time and patience, sure, but it makes for one hell of a shopping center.

Rylie told me to pass on this message:

You can also count Parker Quinn as a recruitable trader, as long as you've got Intimidation or the like to get him into a settlement build zone.

I'm not at recruiting level just yet. Still going back to the beginning to make sure I didn't miss something, or to get a better start. Regarding the doc and random appearances, I went to the campfire she was supposed to be at (according to the Prima Guide book), just outside of Concord on the road south from the Thickets. There were two Raider Scum there getting ready to kill someone who was pleading for his life. They killed him, then told me to go away! I stayed and bothered them a bit and determined there was no doctor there. I found her at a house that I never saw before along the road from Gorski Cabin.

Got her real early, kept seeing her in the house south of that trader station with the drug dealer outside. I'm sure I got staples in that same house. Finally got Anderson at the campfire south of abernathy. Took forever to get the Scribe and I ran out of spawn events for near the police station. Smiling larry involved running to that ghoul hospital and running back, near taffington.

Those two occur on the roaming locations.
1. Between Carla's start and Drumlin
2. The canyon below Ten Pines
3. In Cambridge
4. Malden near the sinkhole
5. Outside the robot shop in South Boston (not Cambridge Watts)
6. Railroad tracks south of Oberland
7. The spot between Mass Turnpike and Danforth encounter.

Those the first few I can think of and there should be around 20 or so.

Doc and Ron are campfire spawns, the majority of the campfires are in Concord area of the map. Only a few going farther south.

Smiling Larry is the hardest one for me to find. Ive seriously only seen him ONCE in 3,000 hours. So.....yes i cheat. When i get 30 settlers in a settlement, i use console commands to have him in my settlement. Hes the only one i can never seem to find.

It's so random! I now can say it's the house off the south road from the Drumlin Diner. Past the green shipping container there is a driveway that leads to the house. Sometimes it's occupied by a pack of mongrel dogs, another time it was occupied by some settlers. I went in there hunting for those dogs because I was hungry, and I'm crouched in the doorway, hidden, then Doc Anderson comes walking out with a friend and they go to the porch and have some drinks like it's a nice pleasant day :) I love this game!!!!!!
